Ice9 Aero PEKK Filament


Ice9 Aero is a PEKK based thermally conductive filament with temperature stability above 250°C. The filament is electrically non-insulating and has a thermal conductivity of 2 W/m-K in the print direction. This filament is ideal for mold tooling and any applications requiring high strength and temperature stability. Ice9 Aero requires a high temperature printer with a hot end temperature 400°C.
